string ConnectionString = System.Configuration.ConfigurationSettings.AppSettings["dsn"];

OleDbCommand com;

OleDbDataAdapter oledbda;

string str;

DataSet ds;

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

bindgrid();

}

private void bindgrid()

{

OleDbConnection con = new OleDbConnection(ConnectionString);

con.Open();

str = "select * from employee";

com = new OleDbCommand(str, con);

oledbda = new OleDbDataAdapter(com);

ds = new DataSet();

oledbda.Fill(ds, "employee");

dataGridView1.DataMember = "employee";

dataGridView1.DataSource = ds;

con.Close();

}

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)

{

txt_sno.Text = "";

bool FirstValue = true;

foreach (DataGridViewCell cell in dataGridView1.SelectedCells)

{

if (!FirstValue)

{

txt_sno.Text += ", ";

}

txt_sno.Text += cell.Value.ToString();

FirstValue = false;

}

}

}

}
